Segments:From the parking lot at Angeles Crest Highway mile marker 54.10, walk south to the PCT trailhead on the east side of the highway and follow the PCT until it lets out at the highway again. Cross the highway and follow the signs for the Silver Moccasin Trail (if you make it to the parking lot, you missed a turn). Follow the Silver Moccasin Trail past Bandito Campground and continue on the next stretch of the Silver Moccasin Trail to the junction with the Horse Flats Trail. Turn right and follow the Horse Flats Trail to Horse Flats Campground. Turn left and you will see the trailhead for the Mt. Hillyer trail and take that to the summit of Mt. Hillyer. From Mt. Hillyer, follow the Mt. Hillyer North Hiker’s Trail down to Horse Flats and follow the road through the campground between campsite 3 and campsite 10 which leads to the trailhead for the Mt. Hillyer Trail (mentioned above). Retrace your steps back to the parking lot.
